Conception....when did this happen?

Question

My last period was 27/12/07. My dating scan and scan after that is dating my due date as 09/10/07. Confused! The dates don't add up and not sure when and where we conceived!!!

Can anyone enlighten me please and thank you very much. :-)

Answer 1

scans are more reliable than LMP if they are done at around 12 weeks. This is because they can measure the leg length and head circumference. Going by the scan due date of 9/10/08 you are 32+6 weeks today and conception would have likely taken place around 12th -21st January

hope this helps

Answer 2

And you have confused me with them dates also

If you mean 08,

Your estimated conception date was between Saturday, January 12, 2008 and Friday, January 18, 2008.

Therefore thats right, as your last period was the month before jan

Answer 3

The dates are note exact, they are best estimates..

Answer 4

Have you got your due date wrong there, you are due before your last period???? DO you mean 09/10/2008 is when you are due?

Answer 5

Your dating scan has put baby just a weeks difference from your dates.  So you would have conceived around 16th Jan.  Hope this helps.  

Answer 6

my last period was 26/12/07 and my due date is 1/10/08... estimating my conception date around the 9th jan...

  Is your cycle a little longer than most? The dating scans are rarely wrong so maybe you ovulated and concieved a bit later than most?

Answer 7

to get the due date, you count 40 weeks from the start of your last period. That would make your due date Oct 10th and conception would have been around January 10th (mid cycle) but more likely before the 10th than after, if you didn't do it on that day.
